2.2.1.2.154 IPBOOTP_IF_BINDING

In the IPBOOTP_IF_BINDING structure, the MIB entry contains the table of IP addresses to which each interface is bound. All of the IP addresses are in network order. The base structure contains the field IB_AddrCount, which gives the number of IP addresses to which the indexed interface is bound. The IP addresses themselves follow the base structure and are given as IPBOOTP_IP_ADDRESS (section 2.2.1.2.155) structures. 

 typedef struct _IPBOOTP_IF_BINDING {
   DWORD IB_State;
   DWORD IB_AddrCount;
 } IPBOOTP_IF_BINDING,
  *PIPBOOTP_IF_BINDING;

IB_State: The state of the IPBOOTP. It MUST be one of the following values.

Value	Meaning
IPBOOTP_STATE_ENABLED 0x00000001	The interface is enabled.
IPBOOTP_STATE_BOUND 0x00000002	The socket is bound and can listen to the IP BOOTP packets [RFC1542].

IB_AddrCount: The number of IP addresses to which the indexed interface is bound.
